Sea Floor Spreading Model Activity Cut Out

The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down.

Sea floor spreading model activity cut out.

Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor. They will also model sea floor spreading at a spreading center such as the mid atlantic ridge. Such magnetic patterns led to recognition of the occurrence of sea floor spreading and they remain some of the strongest evidence for the theory of plate tectonics. The center slit represents a mid ocean ridge 2.
